| 20090117367 | ARTICLE AND ASSOCIATED METHOD - An article includes a membrane having pores and a selectively permeable coating supported by the membrane. The selectively permeable coating includes a hydroxyalkyl-substituted polyalkyleneimine in an amount that is sufficient to chemically react with a chembio agent to reduce the biological activity of the chembio agent or increase an amount of time for a significant amount of unreacted biologically active chembio agent to pass through the article. An associated method is also provided. | 05-07-2009 |
| 20090155564 | ARTICLE AND ASSOCIATED METHOD - An article includes a membrane having pores and that is air permeable. A nanoparticle precursor is dispersed throughout the pores, and the nanoparticle precursor is responsive to a stimulus to form a catalytically active nanoparticle. An associated method is also provided. | 06-18-2009 |
| 20090191357 | PROCESSES FOR FORMING PERMANENT HYDROPHILIC POROUS COATINGS ONTO A SUBSTRATE, AND POROUS MEMBRANES THEREOF - A membrane includes a base membrane; and an electron beam functionalized coating, the coating comprising a polyvinyl alcohol, a polyvinyl alcohol-polyvinyl amine copolymer, a polyvinyl amine, and derivatives thereof functionalized with an electron beam reactive group adapted to form a radical under high energy irradiation. Also disclosed are processes for forming the membrane. | 07-30-2009 |
| 20090191399 | PERMANENT HYDROPHILIC POROUS COATINGS ONTO A SUBSTRATE AND POROUS MEMBRANES THEREOF - A membrane includes a base membrane; and an electron beam functionalized coating, the coating comprising a polyvinyl alcohol, a polyvinyl alcohol-polyvinyl amine copolymer, a polyvinyl amine, and derivatives thereof functionalized with an electron beam reactive group adapted to form a radical under high energy irradiation.
